Description

一种墙体现场发泡胶及隔音隔热墙体
技术领域
本发明属于有机化合物的组合物领域，具体涉及一种含有聚硅氧烷的有机组合物及其应用。
背景技术
保温隔热墙体是由粘结层、基材、锚固件、密封材料等组成，同时具有保温和隔音的功效，已有的隔音隔热墙体构成包括：轻钢龙骨纸面石膏板墙，轻钢龙骨纤维水泥板墙或双层3mm厚钢板，中间填充80mm岩棉。
现有的无机的石膏、岩棉、珍珠岩等保温材料相比，虽然隔热性能好，但隔音性能相对不足，而且填充的隔热隔音材料和基材的结合部位由于材质的不同，膨胀系数不同，遇到冷热环境极易分离脱落，产品的寿命不长。
目前市场用的墙体现场发泡材料主要是以聚酯类为原料，其含有毒气体，易燃，如发生火灾，会给生命和财产造成不可估算的损失。
发明内容
针对现有技术的不足，本发明的目的是提供一种墙体现场发泡胶。
本发明的另一目的是提出由所述墙体现场发泡胶制备的墙体。
实现本发明上述目的的技术方案为：
一种墙体现场发泡胶，是由A组分和B组分组成，其中，
A组分包括质量份的以下成分：主料为50份的三聚氰胺甲醛树脂和40-60份的聚醚多元醇，及30-40份交联剂，4-8份稳定剂，0-2份催化剂，20-40份发泡剂，0-2份溶剂，10-20份阻燃剂；
B组分为200-300质量份的异氰酸酯。
优选地，
所述A组分包括质量份的以下成分：主料为50份的三聚氰胺甲醛树脂和40-60份的聚醚多元醇，及35-40份交联剂，4-8份稳定剂，0.2-1份催化剂，20-40份发泡剂，1-2份溶剂，10-18份阻燃剂；
B组分为200-240质量份的二苯基甲烷二异氰酸酯。
异氰酸酯主要包括甲苯二异氰酸酯(简称TDI)；二苯基甲烷二异氰酸酯(简称MDI)两种。对于墙体材料来说，优选用具有较高强度的MDI。
本发明所述的质量份为本领域技术人员常用的质量单位，例如可以是克，千克，吨，或为了操作方便自定的质量单位。在同一个配方中，“份”表示的单位质量相同。
其中，所述交联剂为聚碳酸酯二醇、聚己内酯多元醇、芳香族聚酯(聚对苯二甲酸丙二醇酯PTT)、己二酸系聚酯(例如环保增塑剂己二酸二辛脂DOA，聚己二酸-1，2-丙二醇酯增塑剂)中的一种或多种。
其中，所述稳定剂为聚氨酯硬泡硅油。聚氨酯硬泡硅油用于增加泡孔细密度和均匀度。聚氨酯硬泡硅油市购可得，例如中山市东峻化工公司产的H-3603、H-3908、H-3609、H-3615、H-3618硅油。
其中，所述催化剂二月桂酸二丁基锡(DBTDL-T12，简称t12)
所述发泡剂为HCFC-141b、正戊烷、一氯二氟、二氧化碳、一氯甲烷中的一种或多种；
所述溶剂为三乙醇胺。
其中，所述阻燃剂选自氯化石蜡70#、聚磷酸三聚氰胺、硼酸锌、五氧化二锑、三氧化钼、磷酸三(1,3-二氯丙基)酯(TDCPP)、三聚氰胺中的一种或多种。
优选地，所述阻燃剂为氯化石蜡70#和磷酸三(1,3-二氯丙基)酯(TDCPP)质量比为1-3：15的混合物。
由本发明所述墙体现场发泡胶制成的隔音隔热墙体。
一种隔音隔热墙体，其是用所述的A组分和B组分混合，喷涂到基材上制成；所述基材为混凝土、木材、塑料板材，金属板材、墙砖中的一种或多种。
本发明的有益效果在于：
因本发明提出的墙体现场发泡胶，具有不燃的特点，主要原料为三聚氰胺，不含任何有毒物质和气体，而且环保。
本发明提出的墙体现场发泡不燃胶添加了闭孔发泡助剂，使墙体隔音、隔热。可根据用户要求在现场施工中增设金属防护网，使墙体增强抗震能力和防破坏能力，现场施工节省了搬运劳动力，使生命财产得到保障。
本发明提出的墙体现场发泡不燃胶，可广泛应用于建筑装饰、装修、老建筑改造领域。
